The present invention provides compositions and formulations comprising metalloprotease enzymes and protein hydrolysate inhibitors that exhibit increased storage stability. In one embodiment, the present invention provides liquid detergent formulations comprising at least one metalloprotease (e.g., Bacillus sp. neutral metalloprotease) that is stabilized by the inclusion of a protein hydrolysate in the detergent formulation. The invention also provides a method for making a protein hydrolysate for stabilizing a detergent formulation by digesting a protein substrate with a metalloprotease enzyme.
L'invention concerne des compositions et des formulations comprenant des enzymes métalloprotéase et des inhibiteurs d'hydrolysat de protéine qui présentent une stabilité de stockage accrue. Selon un mode de réalisation, la présente invention fournit des formulations détersives liquides comprenant au moins une métalloprotéase (par exemple, métalloprotéase neutre de Bacillus sp.) qui est stabilisée par l'inclusion d'un hydrolysat de protéine dans la formulation détersive. L'invention concerne également un procédé de fabrication d'un hydrolysat de protéine pour stabiliser une formulation détersive en digérant un substrat de protéine avec une enzyme métalloprotéase.
